The gorgeous, deep hue of purple sweet potatoes is unlike anything else you’ll have on your holiday table.

The purple comes from anthocyanins, which is the same pigment that gives cherries, strawberries, blueberries, and other red, blue, and purple produce their color.

You can certainly use regular sweet potatoes in this recipe if you’re having trouble finding the purple variety.
